La densidad de drenaje del Valle de la Paz el Carrizal, Baja California Sur y su relación con la recarga de los sistemas acuíferos

The density of drainage, a geomorphometric variable, proved to be an useful tool to make a regionalization of the Valle de La Paz - El Carrizal. This allowed to prospect zones with potential to recharge and/or storing groundwater, as well as to detect possible structural or litological controls on the groundwater flow. Three longitudinal fringes, oriented N-S, composed each one...

Simulación de la degradación por erosión que se observa en los conos de escoria

The volcanic cones known as cinder cones but better described as scoria cones, usually appear in swarms forming volcano fields. They are the smallest type of volcanoes which once unaclive start being degraded by erosion, if we do not consider those that can be buried by material ejected from later nearby cones. The process of degradation is relatively fast at the beginning and...
